STREET-SWEEPING APPARATUS.

SEEGIFICATION forming part of Letters Patent No. 667,132,dated January29. 1901.

Application filed September 29, 1900. Serial No. 31,575. (No model.) A

A a citizen ofthe United States, residing at Iroquois Hotel, in the cityof Toronto, in the county of York and Province of Ontario, Canada, haveinvented certain new and useful Improvements in Street-SweepingApparatus; and I hereby declare that the following is a full, clear, andexact description of the same.

This invention relates to certain new and useful improvements in thatclass of streetsweepers employed in sweeping and cleaning pavements,park-walks, boulevards, lawns, stables,freight-sheds,&c; and the objectof the invention is to so construct the sweeper that it can be easilypropelled and operated and will efficiently and expeditiously performthe duties required of it; and the invention consists, essentially, ofthe device hereinafter more fully set forth and more particularlypointed out in the claim.

In the drawings, Figure l is a side elevation of the street-sweepingapparatus with the parts in their operative position, showing in dottedlines the dust-receptacle in the dumping position. Fig. 2 is a sideelevation from the opposite side to Fig. l, showing the parts intheirinoperative position. Fig. 3 is a plan View of the apparatus. Fig.4 is alongitudinal view through one of the hubs. Fig. 5 is a verticalsection through the same.

Like letters of reference refer to like parts throughout thespecification and drawings.

a represents the axle, fitted with the usual axle-arms, to the innerends of which are keyed circular disks b, fitted with peripheralrecesses c, having inclined bottoms c. Contained in each of the recessesc is a frictionball d, the diameter of which is less than the majordepth and greater than the lesser depth of the recess. Fastened to theouter side faces of the circular disks b are washers a3, each of' whichpartly overlaps the adjacent side face of its respective hub f, thepurpose of the washers being to retain the friction balls d in theirrespective recesses. Mounted on each axle-arm is the hubfof aground-Wheel e, the bore of which lits snugly the rim of the disk. Therecesses are so arranged in relation to the hub and axle that during theforward rotation of the Wheels the balls will roll to the shallower endof the recesses and bind against the bore of the hub and inclinedbottom, causing the united revol ution of the wheels and axle,`andduring the reverse rotation of the wheels the balls roll to the deeperend of the recesses and disengage themselves from the bore of the hub,so that the ground-wheels can revolve without causing a correspondingrevolution of the axle.

Connected to lthe axle a are two rearwardlydirected arms g, onecontiguous to each of the ground-Wheels c. Journaled in the outer endsofthe arms g is the shaft hof the brush 'L'. The brush i can be made ofany suitable size and material. It is preferable, however, to make thebrush of steel bristles, as it has been found in practice that they aremore durable and perform their work more effectively than any otherstyle at present in use.

Keyed on the axle at is a spur-wheelj, which meshes with a spur-wheellc, loosely mounted on a stud l, projecting outwardly from the side faceof the adjacent arm g. Connected to the side face of the spur-wheel lais a sprocket-wheel m, and mounted on the adjacent end of the shaft h isa sprocket-Wheel n. Passing around the sprocket-wheels m and n is asprocket-chain 0, by means of which motion is transmitted from thesprocket-wheel m to the shaft h.

Connected to the axle aintermediate the arms g are the handles p, bymeans of which the sweeper is propelled and operated. Rigidly connectedto each handle p is a brace q. Formed in the lower end of each brace qis a slot fr, and extending outwardly from each arm g is a pin s, whichprojects through the respective slot in the adjacent brace q. By meansof the braces and pins the brush is steadied during its operation and bymeans of the slots r it is permitted to move vertically to adapt itselfto the inequalities of the surface over which it is sweeping.

During the forward revolution of the,

is transmitted by the sprocket chain to the sprocket-wheel n and shaft hof the brush t. The brush t during its revolution sweeps the IOOparticles of dust, the., in advance of the machine.

Looselysuspended from the axle ais a dustreceptacle t, having an openback u opposed to the brush z'. The bottom of the dust-receptacle tclears the pavement over which the apparatus is moving and issufficiently close to the same to enable the brush to sweep the dirt,the., from the pavement into it. Connected tothe top of thedust-receptacle is an outwardly -directed arm e, to which is connectedone end of a link w,-the opposite end ol the link w being connected to acrank y. By drawing the link w toward the ends of the handles p thedust-receptacle can be raised into the position indicated in dottedlines in Fig. 1 of the drawings in order that it can dump its contentswhen it is desired to do so, so that the contents can be placed in areceptacle or in a wagon to be carted away.

When the apparatus is moving over a pavement or surface which is notrequired to be swept, the parts can be tilted into the position shown inFig. 2 of the drawings, which simply consists of turning the handles@ inthe direction indicated by arrows in Fig. l.

This has the effect of reversing the revolufor the operator of theapparatus when going to or from work to use the dust-receptacle for thepurpose of carrying his coat or other parcels.

When lthe apparatus is notin use, it can be set in such a position thatthe handles will be practically perpendicular, in which position it willoccu py but a comparatively small space. The dust-receptacle is of sucha shape that-it will securely hold all dirt, the., that is swept intoit, and by means of the lever the receptacle can be dumped whenever itis fully or partially charged, as determined by the operator.

Having thus fullydescribed my invention, what I claim as new, and desireto secure by Letters Patent, is-

A street-sweeperembracing in ils construction an axle, ground-wheelsmounted on the axle, a friction-clutch interposed between Ithe axle andground-wheels to cause their unitedv rotation during thc forwardrevolution of the ground wheels, rearwardly directed arms connected tothe axle, a brush journaled in the rearwardly-directed arms, adust-receptacle suspended from the axle the opening of which is opposedto the brush, a spur-wheel mounted on the axle, a spur-wheel mounted ona stud intel-meshing with the spur-wheel on the axle, a sprocket-wheelconnected to the spur-Wheel on the stud, a sprocket-wheel mounted uponthe shaft of the brush, a sprocket-chain passing around thesprocketwheels, handles connected to the axle, an arm connected to thedust-receptacle, a dumpinglink one end of which is pivoted to the armand the other end connected to a crank pivoted to one of the handlessubstantially as specified.
